ALEXANDER O. ll/lCBEAN, OF GRAFTON, \VISCONSIN.

RADIATOR.

srE'cIrIoA'rIoN forming part of Letters Patent No. 650,473, dated May29, 19.00.

Application filed June 28, 1899- To ctZZ whom it may concern:

Be itknown that I, ALEXANDER O. MoBnAN, a citizen of the United States,residing at Grafton, in the county of Ozaukee and State of Wisconsin,have invented new and useful Improvements in Radiators, of which thefollowing is a specification.

My invention has for its object to provide simple, economical, durable,and efficient radiators of the heating-drum type, the same consisting incertain peculiarities of construction and combination of partshereinafter particularly set forth with reference to the accompanyingdrawings and subsequently claimed.

Figure 1 of the drawings represents an elevation of my improved radiatorpartly broken away and in section, the plane of the section beingindicated by line 1 1 in the third figure of the series; and Figs. 2 and3, horizontal sections of the radiator, respectively indicated by lines2 2 and .3 3 in the Referring by numerals to the drawings, 4 indicates apreferably-cylindrical shell joined at its ends to flanges of plates 20,provided with central openings surrounded by outwardly-extending flanges5 and 6, around which to fit sections of a stove or furnace draft-pipe,these plates being parts of cast ings embodying flues 8 9, and otherflanged plates 15, the latter plates being of less diameter than thoseaforesaid and joined to the ends of an interposed alsopreferably-cylindrical shell 1. The shells and end castings form theinner and outer casings of my improved radiator, all the joints beingsmoke and gas tight, but readily separable. The flues 8, constitutingparts of the lower end castings, serve for the admission of air into theinner casing of the radiator, and the flues 9 of the upper end castingserve as outlets for said air from said casing. A fan-wheel 10,suspended on a spindle 17, depending from the upper end casting withinthe inner casing of the radiator, serves to retard the flow of airthrough said casing. Legs 14 are shown in connection with the lower endcasting for the support of the radiator clear of the floor of anapartment in which it maybe placed.

Smoke and gas products of combustion as- I Serial No. 722,134. (Nomodel.)

cend through the space 12 between the inner and outer casings of theradiator and are retarded by perforated horizontal plates 13, arrangedat intervals in said space longitudinally of said radiator, these platesbeing shown as provided with flanges secured to shell 1. Theperforations 19 in each of plates 13 are out of line with theperforations in the next adjacent plate or plates, and thus the productsof combustion are caused to have a zigzag course on their way throughthe outer casing of the radiator. By retarding the flow of the productsof combustion through the radiator the air in the inner casing of saidradiator is thoroughly heated. From the foregoing it will be understoodthat the products of combustion passing through the space 12 will raisethe temperature of the air in the inner casing 1, and as the heated airpasses out through the fines 9 there is an inflow of cooler air throughthe lines 8, whereby a circulation of heated air is maintained, while atthe same time there is direct radiation of heat from the externalportions of my device.

The upper end casting being removed, the inner shell 1, with the plates13, may be lifted out and the outer shell 4 may be disconnected from thelower casting, whereby all the parts of the radiator are accessible forcleaning or repair.

Made fast to the upper end casting I show an eye 22, engaged by thevertical shank of an otherwise horizontal bracket 21, the latter beingheld in adjusted position by a set-screw 18, that engages said eyeagainst said shank, this bracket serving as a support for vesselscontaining material to be heated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A radiator comprising upper and lower end castings each consisting ofan outer plate provided with a central aperture surrounded by anoutwardly-extending flange,-an inner plate of less diameter than the oneaforesaid and a series of flues connecting the plates; a shell connectedto the inner plates, another shell connected to the outer plates, andperforated horizontal plates arranged at intervals in the space betweenthe shells.

2. A radiator comprising upper and lower end castings each consisting ofan outer plate provided with a central aperture surrounded by anoutwardly-extending flange, an inner plate of less diameter than the oneaforesaid and a series of fines connecting the platesga shell connectedto the inner plates, another shell connected to the outer plates, andhorizontal plates arranged at intervals in the space between the shells,each plate being provided with perforations out of line with theperforations in the next adjacent plate or plates.

3. A radiator comprising upper and lower end castings each consisting ofan outer plate provided with a central aperture surrounded A, O. McBEAN.
